The 9mm round is a joke.
Their are horrors stories with all calibers especial with ball ammo.
Any body who thinks that getting shot with a 9mm bullet is a joke hasn’t had bullet holes in their body.
Sorry solid hit with any decent round from 22 on up most likely well require surgery and hospital time to recover.
Sorry getting shot is no laughing matter.
The army was fully behind the 9mm, though and a colonel asked at the end of his enthusiastic presentation if there were any questions and I put my hand up. I asked him if the "9mm is the same caliber the Germans lost two wars in a row with" and he told me to "shut up and sit down!" to a room full of laughter.
Afterward, we were led out to a firing demonstration with soldiers in lab coats (making them scientists, I guess) with pistols and the demo was to fire at 55 gallon drums filled with water with cardboard human silhouettes in front of each of them. It was cold, so each barrel had a layer of ice over the water.
Each soldier faced the water barrel/silhouette targets as the narrator (another soldier in a lab coat) described each pistol. The first was a .38 S&W revolver and the soldier fired 6 rounds and made 6 holes and water leaked slowly out of the barrel. The next soldier fired the Beretta 92 and shot a whole bunch of times, turning the barrel into a colander, leaking a lot more.
The last soldier fired one shot with a .45 at the barrel, making a large hole and the silhouette fell to the ground and water poured out like a hose. We Marines cheered and applauded and the demonstration was finished for the day. The army was NOT happy.
